In my application, vibration matters (i.e. I only want the vibration coming from the think I’m mounted too, not vibration caused by flexibility in my mount), so using a single 1/4" screw isn’t enough. Instead, I’m just going to leave a module (or 2) off (cables would make those wasted spots useful again too!) and build a mounting bracket that uses the same thing the modules use to latch on, except maybe with a finger screw to tighten the clamp up instead of a spring.
A blank module housing (like the GPS housing, but with nothing inside it) would work for his. You would just file the antenna connector bubble off, screw the top halve of the shell to whatever you were mounting the bug to, screw the back of the case on and then snap the bug in place.
Have you considered selling empty module housings?
